ROTARY WAX-FINISHING TOOL.

Application filed July 2 1, 1913,'Se1ia1 No. 780,224.

To all whom t may concern Be it known that we, ALBERT M. HoY'r and CARL A. MA'rsoN, citizens of the United States, residing, respectively, at Swampscott and Lynn, in the vcounty of Essex and State of ll'fassachusetts, have invented new and useful Improvements in Rotary VaX- Finishingv Tools, of which the following is a specification.

This invention relates to a rotary tool for burnishing and wax finishing the edges of the heels of boots and shoes. Said tool is particularly adapted to finish the edges of heels by wax treating the same after they have been colored with suitable coloring materi al, but the same .may be used without the wax, to burnish said edges after they have been colored with said coloring material, if it is not desired to use wax in connection with the finishing of said edges.

The object of the invention is to provide a tool of the character set forth which shall apply wax evenly to the edges of the heels of boots and shoes and which will also impart a rubbing. polishing and burnishing action to said edges, which Vtool `is so constructed that it will contain a supply of wat; within itself and will feed Said wax to the periphery thereof in sufficient quantity to supply the necessary amount to the edges of the boot and shoe heels during the wax treating and burnishing operation.

It is also the object of this invention to provide within said tool a means whereby the amount of wax fed to thev peripheryV of the tool may be varied vor graduated.

Moreover, it is the object of this invention to provide a tool of the character set forth which, in addition to feeding waX to the periphery thereof, as hereinbefore set forth, shall preferably have a continuous, yielding, metallic periphery which will acccnnnodate itself to the different curves of the edges of said boot and shoe heels and further it is the object of this invention to provide a tool of the character set forth which shall be cheap to manufacture and durable in its construction.

In wax treating the heels of boots and shoes by means of our improved tool the wax is contained in a chamber Within said tool and is maintained in a melted condition by heat applied in a suitable manner `to said tool. It is desirable in wax treating the edges of boot and shoe heels to rub the heel circumferentiailly thereof and also simul- Specification of Letters Patent. Pat-@niggd Jun@ 20, 1916 Renewed November 30, 1915. Serial No. 64,383.

taneously to rub the heel transversely thereof while lapplying the wax thereto, and it is the object of this invention to provide a tool which shall perform such an operation upon thel edges of boot and shoe heels which are applied to its periphery.

In addition to wax treating the edges of boot and shoe heels by means of our imy proved tool, the same may be used as a burnishing tool pure and simple, that is, it may be used to impart a high luster to the edges of the heels of boots or shoes and can be utilized without the wax if so desired, in which case a coloring material is employed, such as blacking, and the burnishing tool is then utilized to polish or burnish the edge of the heel with this coloring material thereon. In either case, whether by wax treating or by burnishing a colored heel, our improved burnishing tool imparts a high luster and smooth finish to the edge of the boot or shoe heel which is applied to it.

The invention, therefore, consists in a rotary heel burnishing and finishing tool such as described in the followinqv specification and particularly of the construction set forth in the claims.

Referring to the draw-ings: Figure l is a plan view of a portion of a machine for wax treating and finishing the edges of the heels of boots and shoes with our improved rotary heel burnishing and finishing tool attached thereto, the parts being broken away to save space-. Fig. 2 is a sectional elevation taken on line 2--2 of Fig. l, a shoe heel being shown in dotted lines in the proper position relatively to the burnishing tool and the shaft being broken away. Ilig. 3 is a, detail plan of the hollow cylinder comprising a portion of the holder for the rim of the tool. Fig. -lis a detail plan view of the cylindrical valve containing the wax chamber. Fig. 5 is a sectional elevation of a modified forni of burnishing and finishing tool.

Lilie numerals refer to like parts throughout the several views of the drawings.

In the drawings, referring `to Figs. l to -l inclusive, 5 is a shaft mounted to rotate in a suitable bearing 6 and driven by a pulley 7 8 is a rotary tool embodying our invention and consisting of a rim 9, preferably formed of a helical member l0 consisting of a strip of metal bent or rformed as a helix with the .opposite ends thereof fastened7 preferably by welding, to two rings ll -and c cylindrical flange 1,9 thereon.

12, respectively. The ring 11 is fastened by screws'13 to a. cylindrical flange 141 having a hub 15, said hub 15 being fastened by means of a set-screw 16 to another hub 17 which is provided with a fiange 18 having a The ring 12 is fastened by screws 20 to the front end of the cylindrical flange 19. lt will be Vseen that said cylindrical flange 19 constitutes a hollow cylinder, the flange of said hollow cylinder being provided with passages 21 in its periphery extending therethrough and adjacent to the interior of the rim 9.V These passages 21 are preferably disposed in a helical path and midway between the oppo-v site edges of the strip 10. lVithin the hollow cylinder 19 is rotatably mounted a valve 22. Said valve Yis cylindrical and fits closely the inner surface of the flange 19. Said valve consists of an outer wall 23, an inner wall 24 andthe two end walls 25 and 26,

said walls inclosing a chamber 27 adapted to contain wax. Theend wall V2G projects beyond the cylindrical wall 23 to form an annular flange 2,8 which fits the ring 12 and bears against the outer end of the cylindrical flange 19. The inner wall 211 of the f valve 22 is made of a sleeve which has screw- 'threaded engagement with the end walls 25 wrench, into or out of the valve 22. By thus removing the sleeve 21 wax can be packed in the chamber 27 The sleeve 24, being hollow, provides a means whereby a pipe 30 'to supply a gas jet may be introduced in order y-toheat the wax contained in the chamber 27 land also to heat the different portions of the rotary "tool from the inside thereof. This is an important feature in the construction of our improved tool for theV reason that if the tool is heated from the outside the outer parts thereof willexpand, suoli. for instance. as the cylindrical flange 19, before the inner parts, such as the outer wall 23 of the valve, and this will cause the wax to flow too freely from the chamber 27 to the periphery of the tool. lVhen, however, the heat is `applied from the interior, then the walls of the Valve 22 will expand first and make the it between'said valve and the cylindrical flange 19 tighter, thus preventing a. surplus amount of 'wax' from` passing to the periphery of the tool from the Vinterior of the fchamber' 27.

The outer wall 23 of the valve 22 is provided withports'31 in itsV periphery which 'l extend'from thechamber 27 through said wall 23 Vand are preferably disposed throughout the periphery of the valve ina` helical path and are'connected together by ahelica-l groove 32. It'will beunderstood that` the helical groove 32, with the ports 31 opening thereinto, may be set in alineinent with the passages ,2,1 .1.1i the cyliislra] 'wall 19 22 is rotated.

and the parts 22 and 19 locked in position relatively to each other by means of screws 33 which havev screw-threaded engagement with the wall 25 of the valve 22 and project through arcuate slots 25 in the flange 18, said slots being concentric with the hub 17. A spring 33 eneircles each of the screws 33 between the heads of said screws and the flange 1S. Thus the parts 22 and 19 are held locked together against accidental displacement, but may be moved one relatively to the other by means of the wrench or other suitable means applied to the hub 34 of the valve 22, while the cylindrical fiange 19 and the rest of the parts, to which the rim 9 is attached, are held in a stationary position. By rotating the valve 22 in one direction or the Iother, it will be seen that the groove 32 gradually cuts off the opening from said groove into the passages 21, thus making the area through which the wax can fiow from the chamber 27 through the ports 31 along the groove 3J and. outwardly through the passages 21 less or greater according to the direction in which the valve A distributing chamber is preferably provided between the exterior of the fiange 19 and the inner surface of the rim 9, and when the wax passes from the chamber 27 outwardly into said distributing chamber through the passages 21. it will be seen that the centrifugal force will tend to throw said wax against the interior of the rim 9 and as the passages 21 are placed midway between the opposite edges of the strip forming the convolutions of the helical member 10 said wax will tend to strike against the inner surfaces of said convolutions midway between the spaces between said convolutions and thus become distributed over the whole interior of said rim before it passes through the spaces constituting passages for said wax between the convolutions. The holder upon which thi` rim 9 is supported consists, as a whole, of the rings 11 andv 12, the cylindrical flange 19,V the flange 1S, the flange 1l and the hubs 15 and 17. ln order to increase or diminish the space between the convolutions of the helicalmeniber forming the rim 9, screws 36 are provided at intervals around the tool having screw-threaded engagement at one end thereof with the ring 11 and with their heads engaging the ring 12. The natural tendency ofthe convolutions of the helical member 10 is to spring apart. By screwing up on the screws 3G the convolutions of the helical member can be brought nearer to each other or by unscrewing said screws slightly said convolutions will spring apart, thus diminishing or increasing, respectively, the spaces between the convolutions forming said helical member.

The general operation of the rotary tool hereinbefore specifically described is as follows: Assuming the wax Within the chamber 27 to beal in a melted state and to be kept melted by the flame from the gas pipe 30, and also that the tool as a whole is heated by said gas flame from the interior outwardly, a rapid rotation is given to the shaft 5 by the pulley 7 and the tool 8 is rotated rapidly. The Wax is fed through the ports 31 along the groove 32 through the passages 2l into the distributing chamber 35 and thence through the slight spaces or passages between the convolutions of the helical member l to the periphery of said member. The edges of the strip forming the helical member l0 are beveled off, as seen in Figs. l and 2, thus forming a helical groove 37 eX- tending around the periphery of the rim 9 and forming a guide along which the melted wax travels around the whole periphery of the tool. The centrifugal force tends to force the wax from the chamber 27 outwardly through the ports and passages named until it arrives upon the periphery of the tool, where it is distributed over the .l edge of the heel 38 which is held thereagainst and tipped from one side to the other by the operator in a manner Well known to those skilled in the art.

By arranging the groove 32 in the path of a helix, it will be seen that when the.

valve 22 is rotated the passages 2l in the cylindrical flange 19 will be very gradually closed or opened according to the direction in which the valve 22 may be rotated. Thus a very ne distribution and feed of the wax may be obtained to the periphery of the tool.

In Fig. we have illustrated a modified form of our invention in which 89 is the rim formed integral with the flange 40 and hub 4l and also with the cylindrical flange 42. The hub 41 is fastened by a suitable setscrew 43 to a shaft 44 which is rotated in the usual manner. A ring 45 is fastened to the front end of the rim 39 and flange 42, leaving a wax distributing chamber 46 between said rim and flange. It is evident that in this embodiment of our invention the holder upon which the rim 39 is supported consists of the flange 40, hub 41, cylindrical flange 42 and ring 45. A cylindrical valve 47 is rotatably mounted within the cylindrical flange 42 and consists of an outer wall 48, an inner wall 49 and end walls 50 and 5l, said walls inclosing a chamber 52 adapted to contain waX. The inner wall 49 consists of a sleeve having screw-threaded engagement with the end walls 51 and 50 and said sleeve can be removed in order to pack the wax in the chamber 52. The device is heated by means of a gas jet introduced through a pipe 53 and screws 54 serve to hold the valve 47 in position against aceidental displacement relatively to the cylindrical flange 42. The outer wall 48 of the valve 47 is provided with ports 55 and wax passes through said ports and through passages 56 in the cylindrical flange 42 intonthe distribution chamber 46 and from said distribution chamber through small holes or passages 57 in the rim 89 to the periphery of the tool. The adjustment to vary the amount of opening of the ports 55 into the passages 56 is obtained by rotating the valve 47 relatively to the cylindrical flange 42, this construction or' the device being similar to that illustrated in Figs. l to 4 inclusive, but the rim of the tool illustrated in Fig. 5 is a solid rim instead of being yielding and formed of a helical member as in the form of our invention illustrated in Figs. l to 4 inclusive. The operation of the device is similar to that of the device illustrated in Y Figs. l to 4 inclusive and consists in the rapid rotation of the tool, while the centrifugal force causes the wax to pass outwardly through the ports 55 and passages 56 into the distribution chamber 46 and from thence through the holes or passages 57 to the periphery of the rim 39 around which it is distributed and the edge of the shoe heel is held against said rim, whereby the wax is distributed over the edge of the wheel and burnished thereon, the operator tipping the shoe to bring the different portions of the edge of the heel in Contact with the periphery of the rim 39 in a manner well known to those skilled in this art.
